Pumping problem solved

The biggest pumping problem with such heat treatment de-scaling installations is the solid scale particles that invariably bypass filtration stages to some extent in such re-circulating, closed loop systems. Such abrasive particles cause severe damage to pumps that rely on close internal tolerances for efficiency. Seal wear, caused by the finest particles can be expensive and at worst catastrophic for these types of pumps. 
 
Hydra-Cell diaphragm pumps have no dynamic seals to wear and no tight internal tolerances, ensuring long-term efficiency and reliability with no seal maintenance.
 
The Company had good past experience of using Hydra-Cell leak-free, low maintenance pumps but for this particular application the liquid flow requirements were substantially higher than previously encountered.
 
The answer was to use four Hydra-Cell T100K triplex pumps in parallel in order to achieve a flow of 681 lpm at 193 bar pressure. The pumps handle the solid abrasive particles with ease and have proved to be an exceptionally reliable solution.
